Title: Exhaust product recovery device for exhaust emission control system
Inventor: YAMAMOTO ISAO
IPC: F01N3/04
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To effectively recover products in exhaust gas in an exhaust control system which injects fluid into exhaust gas from an engine to capture products residing therein, separates the products and re-injects the fluid thus purified through the separation into exhaust gas, by providing a swirling means for stirring the exhaust gas and the fluid together. SOLUTION: When the engine is running, a fluid force feed part 46 force-feeds the fluid in a fluid tank 26 to a fluid supply pipe 32 and injects the fluid from a fluid injection nozzle 34 into exhaust gas in an exhaust product recovering device 50 to allow the fluid to capture products in the exhaust gas. A filter 44 separates the products incorporated in the fluid to purify the fluid, and the fluid force feed part 46 re-injects the fluid recovered to the fluid tank 26 through a fluid recovery pipe 42 into the exhaust gas from the fluid injection nozzle 34. An exhaust product recovering device 50 is provided, in a purifying chamber 16 in a purifying body 8 of an exhaust purifying system 2, with a swirling means 52 which effectively stirs the exhaust gas and the fluid through the centrifugal effect caused by its swirling motion to allow the fluid to capture products in the exhaust gas.

Title: Molecular-beam crystal growth device and crystal growth method
Inventor: ASAKAWA KIYOSHI
IPC: H01L21/203
Filed: 1989-06-16
Abstract: PURPOSE:To grow a high-purity thin-film crystal with good workability by cracking a raw gas to be cracked in a plasma chamber and introducing the cracked gas into a crystal growth chamber while preventing the intrusion of other raw gases not to be cracked into the plasma chamber. CONSTITUTION:Two or more kinds of raw gases are introduced into the crystal growth chamber 1, and a thin-film crystal (e.g. GaAs crystal is grown on a substrate 5 by molecular-beam crystal growth.

Title: Flywheel device
Inventor: OTSUKA MITSUAKI
IPC: G01L5/28
Filed: 1998-06-03
Abstract: PROBLEM TO BE SOLVED: To rotate a flywheel device at a high speed by preventing the offset and vibration of a rotating body to be caused by the clearance produced between a rotating shaft and the putting sections of a cylindrical section put on the rotating shaft by separating the putting sections from the connecting section of the cylindrical section connected to a heavy section in the axial direction. SOLUTION: Since putting sections 5c and 5d which are put on a rotating shaft 2 are formed at both ends of a cylindrical section 56a and a connecting section 5e connected to a massive section 5b is formed at the left end of the section 5a, the connecting section 5e is separated from the putting sections 5c along the axial direction. When the rotating shaft 2 is rotated, a large centrifugal force is generated in the massive section 5b and a radially outward force is applied to the connecting section 5e of the cylindrical section 5a. Consequently, the left side of the cylindrical section 5a is pulled outward and, as a reaction thereof, the right side of the section 5a is compressed toward the center. Therefore, the inside diameter of the putting section 5d becomes larger, but that of the other putting section 5c becomes smaller.  Accordingly, no clearance is produced between the rotating shaft 2 and putting section 5c and the offset and vibration of a rotating body 5 can be prevented.

Title: Preamplifier device for optical communication
Inventor: KAWASHIMA SEIICHIROU
IPC: H04B10/40
Filed: 1994-07-06
Abstract: PURPOSE:To suppress deterioration of the distortion characteristic of a diode by providing a variable resistance circuit where a distortion corrector means is added in parallel to the feedback resistor of a parallel feedback preamplifier. CONSTITUTION:The input optical signal is converted into a current by a photodetector 1, and the most of the output current of the photodetector 1 is outputted through a feedback resistor 4 or the diodes 5 and 6. Therefore the output signal voltage is proportional to the impedance of a parallel circuit of the resistor 4 and the diode 5. The impedance of the parallel circuit controls the control voltage E1 and E2 in order to control the differential resistances of both diodes 5 and 6. Thus the impedance of the parallel circuit are variable. Then the differential resistances of the diodes 5 and 6 are increased and therefore the gain is increased when the optical input level is low by the control of the voltage E1 and E2. Meanwhile the differential resistance of the diode 5 is reduced when the optical input level is high. Thus the increase of the output level can be suppressed.

Title: Interatomic force microscope
Inventor: SATO AKINOBU
IPC: G01B21/30
Filed: 1991-06-27
Abstract: PURPOSE:To enable observation following a surface shape accurately by providing a mechanism to vary a measuring sample finely in three-dimensional directions in the scanning thereof in two-dimensional directions. CONSTITUTION:A circuit 17 is provided to modulate a signal from a piezo-electric element driving circuit 16 finely so that a measuring sample 12 is varied finely in three-dimensional directions in the scanning thereof 12 in two-dimensional directions of axes X and Y. Then, the sample 12 is moved finely in directions of axes X, Y and Z as each scanning is made and a rate of change in force between atoms is measured. In this manner, it is possible to learn the position of a probe 11 when the force between atoms works between the probe 11 and the sample 12. When there is no change in the force between atoms with fine variation in the directions of the axes Y and Z during a scanning in the direction of the axis X but there is a chance in the force in the direction of the axis X, a step exists in the direction of the scanning. This shows that the force between atoms acts on the sample 12 in front of the probe 11. In this case, the subsequent scanning is performed in the direction of the axis Z. The three-dimensional digital feed back thus arranged enables the following of a surface shape accurately.
